+# QR Code Scanner Script
+
+This script enables users to scan and decode QR codes from image files (PNG and JPG formats). It uses OpenCV and Pyzbar for decoding QR codes and provides a simple file dialog for selecting images on your local machine.
+
+## Requirements
+
+To run this script, you'll need Python 3.x installed on your machine. The required libraries are listed in `requirements.txt`, including:
+
+- **opencv-python**: For image processing.
+- **pyzbar**: For decoding QR codes.
+- **Pillow**: Required for handling image formats.
+- **tk**: Provides a file dialog for image selection.
+
+## Installation
+
+1. **Clone the repository** (or download the script and `requirements.txt` directly):
+   ```bash
+   git clone <repository_url>
+   cd <repository_directory>
+   ```
+2. **Install dependencies:**(Run the following command to install the necessary libraries from `requirements.txt`:)
+
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+## Usage
+
+1. **Run the script** (Execute the QR code scanner script using:)
+   ```bash
+   python qr_code_scanner.py
+   ```
+2. **Select an Image**
+   - A file dialog will open, allowing you to select a PNG or JPG image containing a QR code.
+   - Once an image is selected, the script will attempt to decode any QR code present in the image.
+3. **View the Output**
+   - If a QR code is detected, its contents will be displayed in the terminal.
+
+## Requirements.txt File
+
+The `requirements.txt` file lists all dependencies for the QR code scanner script. This file ensures that the correct versions of each library are installed to avoid compatibility issues. Libraries in `requirements.txt` include:
+
+```bash
+opencv-python
+pyzbar
+Pillow
+tk
+```
+
+Make sure to install these libraries by running pip install -r `requirements.txt` before using the script.
